R.sub.1 and R.sub.2 may be the same or different, with the proviso that R.sub.1 and R.sub.2 are not both CH.sub.3. R.sub.3 is an aliphatic, aromatic arylaliphatic or cycloaliphatic group, which may also contain O, N, S or Si. The ketimine of acetone is subsequently reacted with at least one isocyanate functional crosslinking resin.
